WATER-HEATER.

srncirrcnirroiv forming part of Letters'Patent 1a. 737,525, dated.August 25, mos.

Application filed December 22, 1902. Serial Nol86,1'78. (N model.)

1'0 (066 w/tom it nuty concern:

Be it known that 1, JOHN SUMMERFIELD, a citizen of the United States,residing at Dallas, county of Dallas, and State of'Texas, have inventeda new and Improved Water-Heater, of which the following is aspecification.

This invention relates to improvements in water-heaters; and the objectis to provide heaters by which water for baths and other purposes may beheated in a very short time and which can be manufactured at small cost.

Another object and advantage is that the heaters will also furnishenough heat'to warm a bath-room.

Other objects and advantages will be fully explained in the followingdescription,and the invention will be more fully pointed out in theclaims.

Reference is had to the accompanying drawings, which form a part of thisapplication and specification.

Figure 1 is a vertical section of the heater, showing the invention indetail. Fig. 2 is a plan view.

Similar characters of reference are used to indicate the same partsthroughout both views.

This invention consists of a fire-box A, a

water-tank B, and a pipe E for circulating the water throughout thewatertank. The heater and the tank are preferably cylindrical in form.The heaterA is very large, the vessel A being termed a heater or afirebox, as compared with the amount of fuel that is required. Thewater-tank B circumscribes the heater A, and a pipe E is coiled severaltimes around the heater inside of the tank B for circulating the waterabout the heater. One cover F serves for both the heater and the tank.The heater A is provided with an opening G for putting in fuel and forother p urposes,which openingis closed bya cap H. A pipe connection K ismade with the heater A for conveying away the smoke. Any suitable pipemay be connected with the connection K. The heater is provided with adraft-tube L, which tube is closed by a pivoted damper M. The damper Mis held in close contact or flush with the cover F by means of a buttonor latch N. The tank may be supplied with water through a pipe 0, whichopens through the cover F, which pipe 0 is connected with the pipe E bya T connected with the pipe E without interfering with each other orwith the supplying of the tank with water. The pipe E is passed aroundthe heater several times until it approaches the top part of the heaterand is then brought back practically to the starting-point anddischarges the water in the tank at S.

The tank B is provided with suitable legs I), and the heater or fire-boxA is supported by legs a, which rest on the bottom of the tank B. lVateris heated under the bottom of the heater as well as by the side walls.

The heater A is preferably constructed of copper.

The tank must be filled with water before a fire is started in thefire-box. The tank is filled with water through the pipes I and E orthrough pipes O and E. A fire is then started in the fire-box and thewater out oh"; by cock R. As soon as the water is hot enough it may beforced out of the tank B through a spout or nozzle T by turning in morewater by the cock B. As soon as the cold water is turned in by cock Rthe hot water will commence to run out the spout T. Before the coldwater reaches the spout, the cold water having to pass through the pipeE and then rise up in the tank, it is heated by the heater A.Practically a continuous stream of hot water may be obtained in thismanner. A very small quantity of fuel placed on the floor of the heaterwill heat the water in a very short time. The burning of the fuel may beregulated by the damper M, by which the draft-tube Lmay be opened orclosed or partly closed at will.

The size and shape of the various parts may be varied without departingfrom my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Let-tors Patent, is

1. A water-heater comprising a tank, a firebox mounted in said tank,awater-pipe coiled about said fire-box within said tank, said pipe beingadapted to circulate the water about said fire-box by ascending coilsuntil the water fire-box and then to discharge the water in the lowerpart of said tank near the beginning of the coiling of said pipe, andsuitable smoke and draft connections for said fire-box.

2. A water-heater comprising a tank, a firebox mounted in said tank, awater-pipe coiled about said fire-box within said tank, said pipe beingadapted to circulate the water about said fire-box by ascending coilsuntil the water reaches a point near the upper part of said fire-box andthen to discharge the water in the lower part of said tank near thebeginning of the coiling of said pipe, and acommon cover for said tankand fire-box having suitable openings therein for draft and smokeconnections.

3. A water-heater comprising a tank, a firebox mounted in said tank, apipe, having suitable water connections, coiled about said fireboxwithin said tank, said pipe being adapted to circulate water about saidfire-box by ascending coils until the water reaches a point near theupper part of said fire-box and then to discharge the water in the lowerpart of said tank near the beginning of the coiling of said pipe,a common cover for said fire-box and tank having suitable openingstherethrough for supplying said box with fuel and for making smokeconnection, and a draft-tube suspended in said cover and projecting nearthe 30 bottom of said fire-box.

4. A water-heater comprising a fire-box provided with suitable smoke anddraft connections, a water-tank circumscribing said firebox, and meansfor circulating water about 35 tank, a T- pipe to which said pipes arecon- ;0

nected, and a pipe connected to said T- pipe and coiled about saidfire-box in ascending coils to the upper part thereof and then bent backnear said T- pipe.

In testimony whereof I set my hand, in the 5 presence of two witnesses,this 15th day of December, 1902.

JOHN SUMMERFIELD.
